Mild Tuesday Snow Gives Way to Cold, Wind, and Blowing Snow

Brad Leave a comment

A low pressure system moving through southern Manitoba will bring snow and mild temperatures to the Red River Valley. In its wake, colder temperatures and strong winds will surge into the region.

RDPS 10m Wind Forecast valid 15Z Wednesday December 4, 2024
Strong winds will develop across the Red River Valley late Tuesday into Wednesday, likely producing widespread blowing snow across the region.

Apologies for the late forecast, life has been busy!

Snow spread across much of southern Manitoba this morning as a low pressure system pushed a warm front into the region. A burst of moderate to heavy snow has moved through the region this morning, and now milder temperatures will spread across the region with daytime highs of -5 to 0 °C across southern Manitoba. As the warm air moves in, stiff southerly winds will shift to lighter westerlies.

A cold front will sweep through later today, ushering in some light snow and a major shift in the weather. Temperatures will plummet into the minus teens tonight as northwesterly winds strengthen into the 40 to 50 km/h range with gusts of 60 to 80 km/h. It’s likely that lake-effect snow will develop off the lee of Lake Manitoba and Lake Winnipeg, producing a band of flurries that could last well into Wednesday.

The colder temperatures, new snow, and strong winds will likely produce widespread blowing snow across the region, though limited snowpack inside of Winnipeg could reduce the overall amount of blowing snow within city limits. Of particular concern will be the Trans-Canada Highway corridor between Winnipeg and Portage la Prairie where strong winds, existing snow, and lake-effect snow could combine to produce white out conditions and potential highway closures heading through Wednesday.

With those strong northwest winds, temperatures will only recover a couple degrees on Wednesday before dropping down to a low in the -20 to -25 °C range on Wednesday night. Wind chilled values will likely hover in the -25 to -30 range all day then closer to -30 overnight as the wind dies off.

A ridge of high pressure over the province on Thursday should bring partly cloudy skies to the region, light winds, and highs in the mid-minus teens.

Long Range Outlook

Another notable pattern shift will occur late this week as a strong low pressure system is forecast to track across the southern Arctic. This system will send warmer air sweeping across the Prairies, sending daytime highs back towards the 0 °C mark on the Weekend. More snow looks possible eon Sunday as a cold front pushes through the region, then it looks like a return to near-seasonal conditions for much of next week.

Today’s seasonal daytime high in Winnipeg is -7 °C while the seasonal overnight low is -16 °C.

Sunshine Reappears in Winnipeg…Briefly

The sun will finally make a reappearance in Winnipeg today as colder weather moves into the region.

RDPS 2m Temperature Forecast valid 12Z Saturday November 30, 2024
Winnipeg will see chilly overnight lows near -20 °C in the days ahead, but it will be much colder to the west.

Morning cloud cover will give way to sunshine today as the never-ending blanket of stratus cloud finally moves out of the region. The minor cost to finally kicking some of the gloom that’s set in is that temperatures will drop across the region. In Winnipeg, temperatures will hover just below -10 °C today with norhtwest winds steady around 30 km/h.

The winds will ease to around 20 km/h tonight with temperatures dropping close to -20 °C. A bit of lake-effect cloud and snow is possible off of the Manitoba Lakes, so Winnipeg could find itself with mixed skies through the night and perhaps some scattered flurries. Between the wind and the vicinity cloud, it’s unlikely that temperatures will drop much below -20 °C, if at all.

Much colder temperatures will sit just to the west of the Red River Valley; overnight lows in the -25 to -35 °C range will straddle the Saskatchewan/Manitoba border over the next couple nights.

The next couple days in Winnipeg will likely look much the same; cloud drifting into the region from the northwest as it pours off Lake Manitoba in the freeze-up process, possibly with some light snow. Highs will range from just below -10 °C under clearer skies to just over -10 °C under cloudier skies. Overnight lows could be in the -10 to -15 °C range if the band of lake cloud parks itself over the city at night, while it could drop closer to -20 °C if it clears.

Conditions may trend sunnier on Sunday as winds shift more northerly which would shift lake-effect cloud bands out of the Winnipeg area.

Long Range Outlook

Looking ahead, a low pressure system is likely to move through the region Monday night through Tuesday. Dropping down from the northwest, it looks to bring 5 to 10 cm of snow to central Manitoba with amounts diminishing southwards. It will come with a push of colder air, so there is still uncertainty with its track. This system will likely produce a swath of 5 to 15 cm of snow, but whether that occurs through central Manitoba or along a strip from the Parkland through the Red River Valley is unclear at the moment.

Behind this system, a push of colder air will move into southern Manitoba and send temperatures colder through the second half of the week.

Today’s seasonal daytime high in Winnipeg is -6 °C while the seasonal overnight low is -15 °C.

Cooler, Cloudy Weather Ahead for Winnipeg

The Winnipeg area will stay smothered in cloud cover this week as temperatures gradually cool.

RDPS 2m Temperature Forecast valid 21Z Thursday November 28, 2024
While temperatures will drop in southern Manitoba this week, the region will avoid the bitter cold that will move through the western Prairies.

The Winnipeg area will be stuck under a blanket of cloud cover this week thanks to a stagnant flow over the region. Winds will stay light over the next few days as a weak ridge of high pressure stalls over southern Manitoba.

While an occasional sunny break may be possible, it looks like skies will stay mostly cloudy to overcast for the next several days.

Daytime highs will hover around -6 °C over the next couple days with overnight lows close to -10 °C. With temperatures in this range, flurries will be possible over the next couple days as well.

A cold front will slide through the area on Thursday, bringing breezy northwest winds and cooler temperatures. Winds should climb up to 30 gusting 50 km/h on Thursday as colder air pushes in. Temperatures will struggle to break -10 °C and then head down into the mid-minus teens on Thursday night. The cooler temperatures will make flurries less likely, but with the push of colder air there will be a chance that some lake-effect snow streams off Lake Winnipeg and Lake Manitoba.

Long Range Outlook

Heading into the end of the week, skies will likely stay mixed to mostly cloudy right through the weekend. Some sunshine is possible, but will more likely be through breaks in the cloud and any widespread clearing.

Temperatures will hold relatively steady with highs in the -15 to -10 °C range and overnight lows in the -20 to -15 °C range. Now that the city has snow on the ground, it will be much easier for temperatures to drop overnight, especially under any clearing that could develop.

Winds will gradually ease and there could still be some more flurries, but with the likelihood dropping along with the temperature.

Today’s seasonal daytime high in Winnipeg is -5 °C while the seasonal overnight low is -13 °C.

Mild Fall Stretches On

Brad Leave a comment

The mild fall conditions seen across southern Manitoba will continue into mid-November. There will be weather, though: after a blustery Tuesday, Winnipeg will see several chances for rain over the next week.

RDPS 10m Wind Forecast valid 18Z Tuesday November 12, 2024
Strong southerly winds will develop over the Red River Valley today.

Temperatures will stay well above seasonal values in Winnipeg this week as mild air continues to flood into the southern Prairies. While winter weather isn’t that far away — the farther reaches of northern Manitoba and southern Nunavut have seen temperatures near -20 °C or colder already this year — that cold air won’t be making its way south any time soon.

Rather, winds will stay more southerly and westerly over the coming week, bringing daytime highs 5 to 10 °C above seasonal values and keeping overnight lows equally mild.

Starting off with today, it will be a seasonably mild day but marked most notably by strong southerly winds. with the region squeezed between a high pressure system to the southeast and a low pressure system in northern Saskatchewan, southerly winds will strengthen into the 40 to 50 km/h range today with gusts as high as 70 km/h through the Red River Valley. Temperatures will climb to a high near 7 °C this afternoon as skies cloud over.

Cloudy skies will continue through the night as southerly winds gradually taper off into the 20 to 30 km/h range. The cloud and wind will keep things mild with lows dipping just below 5 °C.

On Wednesday, temperatures will rebound back into the upper single digits as a trough of low pressure moves through the region. That trough will bring a chance of some light midday rain showers that clear out of the region for the afternoon. Some sunny breaks are possible as skies likely clear out heading towards the evening. Those southerly winds will also ease in the morning, then switch to light northwesterlies behind the trough.

Temperatures will head to a low near freezing on Wednesday night with light winds and clear skies. Some fog patches could develop overnight and last into Thursday morning.

On Thursday, more cloud will develop over southern Manitoba as another low pushes into Saskatchewan. Temperatures will again climb into the upper single digits as winds shift back out of the south and strengthen into the 20 to 30 km/h range. The low in Saskatchewan will lift northeast through the day, lifting its warm front with it and bringing the Red River Valley into its warm sector. This should bring clearing skies on Thursday night with a low in 0 to 5 °C range and southerly winds of 15 to 20 km/h.

Long Range Outlook

On Friday, Winnipeg should see a beautiful mid-November day in the warm sector of the low tracking through the province. Daytime highs could be as high as +10 °C with sunny skies and a southerly breeze.

The warm weather will persist into the weekend, but another low moving into the area will bring cloudier skies with a good chance of rain on Saturday. Conditions will settle on Sunday with mild weather lasting right into Tuesday.

Tuesday/Wednesday next week will likely bring more rain to the region with temperatures likely beginning to cool off behind it. That said, there’s quite a bit of discrepancy in the guidance at this point; some keep it relatively mild, while others bring a sharp cold snap into the region.

Either way, there’s at least another week of pleasant, mild November weather ahead. Hope you can enjoy it!

Today’s seasonal daytime high in Winnipeg is -1 °C while the seasonal overnight low is -8 °C.
